Shocking shocking Service, no one knows whats going on no-one helps

So I signed up with Supersonic as they are backed by a giant Telecomms company MTN, my Vumatel line has since been installed and I have phoned support, billing sales everyone, i have call logs of almost 4 hours trying to get my line activated, I have still not received my router but I have my PPPOE settings, they dont work, sending a message on whatsapp line has a response time of about 4 hours, after which I receive a mail stating that my line will be installed in 7-14 working days, its already installed. I have no online log in and this will be day 2 of taking leave as from the 30th of June my previous internet contract ended, which I informed the sales agent the previous week already as well.
